-LRB- CNN -RRB- -- New Jersey Lt. Gov. Kim Guadagno is expected to `` categorically deny '' allegations Monday that she gave Hoboken 's Mayor an ultimatum regarding Superstorm Sandy recovery aid .

Guadagno 's denial flies in the face of claims made by Hoboken Mayor Dawn Zimmer , who said Sunday that Guadagno told her to support a redevelopment project backed by Christie or lose Sandy recovery funds .

Zimmer also connected Christie to the threat , saying that Guadagno told her the message was coming directly from Christie .

Appearing on CNN 's `` State of the Union , '' Zimmer said , `` She said that to me -- is that this is a direct message from the Governor , '' Zimmer said , referring to Lt. Gov. Kim Guadagno , who Zimmer said approached her in a parking lot in May to deliver the message .

Hoboken mayor : ` It 's true ' Christie administration withheld Sandy funds

The alleged incident happened last May after Guadagno toured a grocery store that had reopened after suffering $ 10 million in flooding damage from Sandy .

The lieutenant governor recalls having a conversation with Zimmer that day , but says she remembers Zimmer arguing that Sandy recovery aid and redevelopment were the same issue , according to the source close to Guadagno , who was not authorized to speak publicly .

`` Kim remembers in their conversation that she was talking about redevelopment and making investments in Hoboken . She remembers Zimmer pressing Kim for money for Sandy . Kim remembers saying you ca n't tie the two together , '' the source said . `` And she remembers Zimmer continuing to press and showing her a map of the city and pressing for aid for Sandy . ''

Catching up with the Christie scandal

Guadagno remembers it as a `` friendly conversation , '' the source said . `` Zimmer was laser-focused on getting Hoboken money for Sandy recovery and that is not the role Kim Guadagno plays in the administration , '' the source said .

She remembers telling Zimmer that the administration would like to do more to redevelop Hoboken , but she does n't recall talking to her specifically about The Rockefeller Group project . But the source said Guadagno , a veteran prosecutor and former county sheriff , is still going through her records , preparing for a possible subpoena .

In remarks Monday morning -- at a volunteer event in Union Beach , New Jersey honoring the Martin Luther King Jr. . National Day of Service -- Guadagno is expected to make the point that , `` My job in the governor 's office is to oversee redevelopment and reinvestment in New Jersey , '' the source said .

In fact , a governor 's directive prevents Guadagno from working on the Sandy recovery efforts because she was personally affected by the superstorm -- her home in Monmouth Beach was damaged by the storm , the source said . She was at the Hoboken grocery store in her role as an advocate for the state 's business community .

`` Kim ca n't talk about Sandy , '' the source said . `` She ca n't do it . ''

And Guadagno twice returned to Hoboken after that May visit -- once spending more than two hours touring farmers ' markets with Zimmer -- and the Hoboken mayor never brought up the May conversation or indicated that it had upset her , the source said .

Zimmer 's comments Saturday and Sunday are a change from what she told CNN on January 11 . She said then that while she wondered whether Sandy aid funds were being withheld because she did n't endorse the governor 's re-election , she concluded that `` I do n't think that 's the case . ''

`` I do n't think it was retaliation and I do n't have any reason to think it 's retaliation , but I 'm not satisfied with the amount of money I 've gotten so far , '' Zimmer told CNN then . She did not mention her concerns about the redevelopment project .
